JOURNAL-BEARING.

SPECIFICATION forming part of Letters Patent No. 655,633, dated August '7, 1900.

Application led March l0, 1900. Serial No. 8,167. (No model.)

like machines as to provide for the secure retention of the roller or pulley in place when in use, but permit of the ready removal of the roller-journals from their bearings when necessary. This object we attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which- Figure l is a plan or top view of a journalbearing constructed in accordance with our invention, illustrating its application to a form of pulley or roller carrier common in spinning and Winding machinery and showing one of the journal-retaining caps in its normal position and the other swungback out of the way. Fig. 2 is a transverse section, also showing one of the journal-retaining caps in position and the otherfswung back. Fig. 3 is a section on the line a a, Fig. l. Fig. 4: is a view similar to Fig. 3, but illustratinga slight modification of the invention. Fig. 5 is a view, partly in elevation and partly in transverse section, illustrating another embodiment of our invention; and Fig. 6 is a transverse section on the line ff, Fig. 5. i

In Fig. l We have shown at l a form of forked hanger or yoke common in spinning and Winding machinery, the opposite legs of this yoke having boxes 2 for the journals 3 of a roller, pulley, or other element of the machine, the element shown at 4 being a roller, although the invention is equally applicable to bearings for the journals of a beltdrum. 4

The journals 3 are adapted to bushings 5, which are preferably ofspecially-prepared woodfor other material which does not require lubrication, these bushings by preference fitting snugly into the boxes 2, so as to be prevented from turning therein, the jour nals turning in the bushings, although in some instances the reverse may be the case that is to say, the bushings mayiit snugly to the journals and may turn in the bearings.

The bushings can be introduced into and withdrawn vertically from the bearings, so that the roller 4, after having the bushings 5 applied to its journals, can be readily dropped into or lifted out of place or the bushings may be slipped laterally onto the journals after 'the latter have been introduced. into the boxes.

Each of the bushings is normally held in position in its box by means of a swinging cap 9, Which has a pivot-stern l0 passing through au opening in a lug ll on the box and having at its lower end a suitable head or enlargement, upon which acts a coiled spring 12, interposed between said head and the lu g and tending to press the stem and likewise the cap 9 downward, so as to prevent accidental rise of the cap, although'the Weight of the cap and the fact that the pivot-stem is not'centrally disposed may be relied upon to prevent such rise in some cases, as rising movement of the outer portion of the cap would tend to jam the pivotstem in the opening in the lug ll of the box. Each cap has at the outer end a depending plate 13 for bearing against the end of the box 2 and preventing any lateral outward movement of the bushing 5, and each cap also has a portion 14, which enters the top of the box and engages with the front and back portions of the same, as shown in Fig. 3. When the caps are in their normal position, therefore, they securely retain the bushings in the boxes both vertically and laterally, and in order to release either bushing it is necessary to iirst lift the caps until the depending portions 14 of the same are free from engagement with the front and back portions of the boxes, the caps being then free to be swung around on their pivotstems lO to the position shown at the right-hand side of Fig. l and also at the right-hand side of Fig. 2, so as to uncover the boxes and permit of the lifting of the roller 4 and its journal-bushings out of the boxes.

Vhen either of the caps 9 is swung around out of retaining position, the-pivoting-heel 93^ roo of the cap rests upon a rib l5 on one of the legs of the yoke and is thus supported in position to be again swung back over the box, downward pressure of the spring 12 upon the stem of the cap causing such friction between the under side of the cap and the top of the rib as to eiiectually prevent the shaking or other accidental movement of the cap from its retracted position. It will be evident, however, that the lug 1l of the bearing might be such that the portions 14 of the cap would bear upon the same when the cap was swung around to the open position, and it is equally evident that the cont-act of the heel 9a and rib 15 or equivalent construction may be relied upon in place of shoulders 14 on the cap to render necessary the lifting of the cap before it can be swung around. This necessity of lifting the cap before it can be moved out of retaining position precludes a possibility of theaccidental shifting of the cap from such retaining position.

kWhere the roller or pulley t is not subjected to any upward strain, a slotted bushing-such, for instance, as that shown at 5 in Fig. 4;-may be employed, this bushing being secured within the box 2 in any appropriate manner and the journals 3 of the roller or pulley 4c being dropped into or lifted from the slotted portion of the bushing when the caps 9 have been swung around out of the way.

In Figs.V 5 and 6 we have shown a further embodiment of our invention, the bushings 5 in thiscase being fitted to segmental transverse openings or recesses in the boxes 2, so as to be readily insertible laterally into or removable laterally from said openings, although preferably they iit so snugly therein that'they are not free to turn, the journals 3 turning in the bushings.

LSlots 6 extend from the tops of the seg `mental openings .which receive the bushings 5.l up to the tops of the boxes 2, these slots being less in width than the diameter of the bushings, but equaling or exceeding i'n width the diameter of the journals 3.

TheA boxes 2a are recessed at top and bot tom vfor thereception of an elastic retaining clip orcap 7, which consists, preferably, of a piece of elastic sheet metal bent so as to embrace the outer side, top, and bottom of each box, said cap having lugs 8, which overlap the inner side of the box, as shown at the left-hand side of Fig. 5. Hence when these caps are in iplace the journals of the roller orpulley are properly held in their bearings, since the bushings 5 can only be drawn outward laterally from the openings in the boxes 2, and suc-h lateral withdrawal of the bushings is necessary before the journals 3 can be lifted from the boxes through the slots 6 in the top of the latter.V Lugs on the boxes for engagement with openings in the cap '7 may, if desired, be employed instead of the reverse construction shown.

.Vthen lit is desired to remove the roller or pulley, the spring-caps are slipped off, as shown at the right-hand side of Fig. 5, the

bushings 5 are withdrawn laterally, aifd the roller or pulley is then removed vertically, reapplication of the parts being eected by a reversal of these operations.

Each of the caps 7 may, if desired, have but a single retaining lug or shoulder 8 to prevent accidental displacement, and in like manner the caps 9 may each have but a single retaining-shoulder, the double shoulder being preferred, however, in all cases.

If the boxes 2 are closed at their outer ends or other provision is made for holding thejournals orbushings against lateral movement, the provision of the end plates 13 upon the caps 9 will be unnecessary, said caps simply conning the bushings 5 vertically in the boxes, as vertical removal of the bushings in this case would be the only permissible one, and if the boxes 2 are contracted at the top,'soas to vertically confine the bushings,'or', in other words, are made as shown 'at 2, lthe swinging caps 9 may be provided with end plates 13, but need not necessarily extendacross the top of each box, any desired portion of the cap engaging with a shoulder on the bearing,or vice versa,in order to compel the lifting 'of the cap before it can be swung around.

Each cap by preference, however, completely covers the top of the box, so as to prevent, as far as possible, the access of ,dust and dirt to the bushing and journal of the roller.

Our invention is also applicable to bearings lin which the journalsv are not provided with bushings-for instance, toa bearing in which the journals are seated directly in the boxes and are prevented .from being lifted therefrom by the removable Vcaps orfeovers.

Having. thus described our invention, we claim and desire to secure by Letters Patent- Y Y l. The combination of the journal-box with a retaining-cap therefor having a portion for closing the box so as to prevent removal of the journal therefrom, said cap being movable in one direction to release lthe journal',

but having a portion engaging with the box or its carrier and necessitating movement of said engaging part in a different direction before the cap can be moved out of retaining position, substantially as specified.

2. The combination of the j ournal-box with a retaining-cap therefor having a portion for closing the box so as to prevent removal `of the journal therefrom, said cap being movable in one direction to release the journal but having a 'portion engaging with lthe box or its carrier and necessitating movement of said engaging part in a different direction before the cap can vbe ,moved out of retaining position, and elastic provision for maintaining said engaging part in engagement, substantially as specified.

3. The combination of the journal box, bushings receiving said journal 'and fitting in said box, and a retaining-cap havinga portion forvclosing the box so as to prevent removal of the journal-bushing therefrom, said loo IIC;

'cap being movable in one direction to release the journal-bushing but having a portion engaging with the box or its carrier and necessitating movement of said engaging part in a diiferent directionA before the cap can be moved out of retaining position, substantially as specified.

4. The combination of the j ournal-box with a retaining-cap therefor having a portion for closing the box so as to prevent removal of the journal therefrom, said cap being pivoted so as to be movable in one direction out of retaining position but having a portion transverse to the axis of the pivot and engaging with the box or its carrier and necessitating movement of saidengaging part in a direction different from that of the swinging movelment before the cap can be swung out of retaining position, substantially as specified.

5. The combination of a journal-receiving box with a removable cap therefor having a pivot-stud and a shoulder transverse to the axis of the pivot for engagement with the box whereby a vertical movement of the cap in order to free said shouldered portion is necessary before the cap can be swung around out of its retaining position, substantially as specified.

6. The combination of a journal-receiving box with a removable cap therefor, having a pivot-stem, a plate for closing the end of the box, and a shoulder transverse to the axis of ithe pivot for engaging with the top ofthe box, whereby vertical movement of the cap in order to free the said shouldered portion from the box is necessary before the cap can be swung around out of retaining position, substantially as specified.

7. The combination of the journal-box with a retaining-cap therefor having a pivot-stem and a spring acting to depress the cap, said cap having a shoulder transverse to the axis of the pivot for engagement with the box and necessitating movement of the cap before it can be swung around out of retaining position, and a support for retaining the cap in the elevated position when thus swung around and for exerting such friction upon the cap as to prevent it from being accidentally swung back into retaining position, substantially as specified.

In testimony whereof we have signed our names to this specification in the presence of subscribing Witnesses.
